• Cost: $5,000 – $7,000+

Used Containers:

• Have been in circulation for years.
• May have cosmetic wear or minor rust, but still structurally sound.
• Cost: $2,500 – $4,500

Pros of New Containers:

• Clean and ready for custom modifications.
• Longer lifespan.
• Often include warranty.

Pros of Used Containers:
